Adapt terrain to road?

Question

Hello, 
 I'm trying to adapt a terrain I have modelled from elements to a road. 
 How would you proceed? I would like to make my terrain follow the roadway that I have also modelled. 
 If anyone could give me any input it would be greatly appreciated.

I think this is what you mean. 
 1. You have an existing terrain. Have you made the existing terrain the 'ACTIVE' terrain? The road end conditions will then target this terrain. 
 2. You have a proposed road. The existing terrain will be under or over the road depending on whether you are in cut of fill. 
 3.The existing terrain will not change because of the road. 
 4. You will need to create a clipped terrain from the exting terrain i.e. use the proposed road to 'cut a hole' in the existing terrain, so that the road can sit in the hole to give you an 'as-built' view of the scheme.
